Analysis of Uncertainty in Standard Metal Tank Volume Verification with Monte Carlo Method

Abstract:

The uncertainty in standard metal tank volume value verification is evaluated by using Monte Carlo Method. For second standard metal tank, verification is conducted with volume comparison method. A mathematical model of second standard metal tank volume measurement is established by using first standard metal tank to measure second standard metal tank. An analog simulation is conducted for verification value by using Monte Carlo simulation method, and hence the uncertainty in volume verification is obtained. Through comparison between evaluation result and traditional uncertainty propagation evaluation method, the result indicates that the difference cannot be ignored and the evaluation result by using Monte Carlo Simulation Method is more reliable.
